SSR Static Switch

A complete solution for driving electrical loads. It has a heatsink, fan, overheating protection, attachment, and connections suitable for the rated current. It uses SSR, an electronic device that has several advantages over standard electromechanical relays (contactors), as a switch. A command signal (INPUT) triggers the load connected to the power terminals (LOAD).

Since they have no moving parts, there is no wear or mechanical operating noise. The zero-crossing actuator reduces electrical switching noise. Electrical isolation between input, output, and metal housing simplifies and ensures safer installation and maintenance. Properly installed, they can operate without failure for many years. Control with electric pulse: 4 to 32 V. Load voltage: 480 Vac. Currents: 80 to 300 Amperes.
